Probably one of the scariest villains in recent K-Drama history is the character portrayed by Kwak Si-yang in the SBS drama Good Partner, who takes his portrayal of a two-faced character to a chilling extreme.

In recent episodes that aired on Sept. 6 and 7, Kwak Si-yang's character, Cheon Hwan-seo, who is the chairman of the Cheon Medical Foundation, shocked viewers when he was accused of domestic abuse by his wife, Yoo Ji-young, who is filing for divorce.

Cheon tries to argue that her wife is only after his money. The hot chairman was initially portrayed as a loving husband, only to be later revealed that he is a two-faced abuser who constantly tortures his wife with water. His rage eventually ends up killing her.

The moment Cheon goes from a loving husband to the cruel man who splashes water on her wife in a fit of rage, as well as his transition to murder her, showcases Kwak's impressive acting skills.

However, the best scene in Good Partner is when Cheon threatens the legal counsel with execution and the other characters, Jang Na-ra and Nam Ji-Hyun, who try to protect his interests.

It is arguably Si-yang's best turn at a villain character in his acting career so far, considering that he has been around for some time and often played villains.

Kwak Si-yang's new movie, 6 Hours Later You Die, filmed in Mexico, will premiere in October.
